-if -H 'IMPROVEMENT IN WASH-BOILERS.

The Schedule referred to in these Letters Patent and makix'ag part 0f the same.

To a'll whom 'item1-y concern Be it known that I, HARVEY T. WOODMAN, of Dubuque, in the count-y of Dubuque and State of Iowa, have invented a new and improved Wash Boiler; 'and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others to make and use my invention, reference being had to the accompanying drawing forming,r part of this specification, in which- Figure 1 represents aver-tical transverse section of my improved wash-boiler.

Figure 2 is a plair or top view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish the pub-v lic with an improved wash-boiler, of the kind in which vertical tubes areprovided for conveying the water, when heated, at the bottom of the boiler, to the npper part of the'same, where it is discharged upon the clothes.

The improvement consists in an` arched perforated false bottom, between which and the true bottom of the boiler the water will be heated, and whence it will be forced upward in the tubes, it being also provided with shoulders to support a slotted plate, which is to be removed when, from. any cause, it is desirable to place the clothes nearer the re or bottom of the boiler.

A in the drawingr represents a wash-boilerof suitable size, shape, and material. lVithin the same are secured, to the sides and ends, or either, vertical plates a a., which constitute vertical pipes or passages b b, that are open at both ends.

The lower end of each plate a has an inwardly-projecting flange, c, from which the false bottom B is s uspended, as shown in4 fig. 1, the saidfalse bottom being arched, and provided with perforated upright borders d, as shown.

A perforated bottomor slotted plat-e; C, is, on shoulders e of the borders (l, supported by the false bottom lInstead of having the plates a within the boilers,

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The archedand laterally-perforated false bottom B,
